MAX4062EUB+T
Differential Microphone Preamplifiers with Internal Bias and Complete Shutdown
General Description
The MAX4060/MAX4061/MAX4062 are differential-input
microphone preamplifiers optimized for notebook and
PDA audio systems. These devices feature adjustable
gain with excellent power-supply rejection and com-
mon-mode rejection ratios, making them ideal for low-
noise applications in portable audio systems.
The MAX4060/MAX4062 are capable of switching their
output between the differential input and a single-
ended auxiliary microphone amplifier input. In addition,
the MAX4060/MAX4062 have a low-noise microphone
bias generator. The differential gain of the
MAX4061/MAX4062 is set with a single resistor. The
MAX4060 has a fixed gain of 10V/V and is PC99/2001
compliant. The MAX4061 includes a complete shut-
down mode. In shutdown, the supply current is
reduced to 0.3µA and the current to the microphone
bias is cut off for ultimate power savings.
The MAX4060 operates from a 4.5V to 5.5V single sup-
ply and the MAX4061/MAX4062 operate from 2.4V to
5.5V. All devices are specified over the extended oper-
ating temperature range, -40°C to +85°C. The
MAX4060/MAX4061 are available in tiny 8-pin TDFN
(3mm x 3mm x 0.8mm) and 8-pin µMAX®packages.
The MAX4062 is available in a 10-pin µMAX package.

Detailed Description
The MAX4060/MAX4061/MAX4062 are differential micro-
phone preamplifiers providing high-quality audio, opti-
mized for use in computer and mobile applications.
These devices feature rail-to-rail outputs, very high
power-supply rejection, and common-mode rejection,
making them ideal for low-noise applications. The
MAX4060/MAX4061/MAX4062 are particularly effective
when layout constraints force the microphone amplifier to
be physically remote from the ECM microphone and/or
the rest of the audio circuitry.
The MAX4060/MAX4062 are capable of switching their
output between the differential input and an inverting
single-ended input. INT/AUX selects either the differen-
tial input or single-ended auxiliary input. In addition, the
MAX4060 has an internal bias generator to bias the
microphone in either differential or single-ended
modes. The MAX4061 includes a complete 0.3µA shut-
down mode for ultimate power savings. The differential
gain of the MAX4061/MAX4062 is set with a single
resistor connected between the G1 and G2 pins. The
MAX4060 has a fixed gain of 10V/V.
Differential Input
The main microphone input is a low-noise, differential
input structure. This is an almost essential element
when faced with amplification of low-amplitude analog
signals in digitally intense environments such as note-
book PCs or PDAs. Used correctly, the advantages
over a single-ended solution are:Better power-supply noise rejection.Less degradation from noise in PC board ground
planes.The microphone and preamplifier can be placed
physically further apart, easing PC board layout
restrictions.
